組織工程支架為一多孔性支架,可提供很好的環境讓細胞貼附生長、分化和形成細胞外間質(Extracellular Matrix , ECM),文獻指出骨再生所需之最佳孔徑為350μm以下,但卻無法得知於此範圍內,孔徑大小對細胞成長的影響。
因此,本研究針對骨再生所適合成長之最佳孔徑範圍內,利用快速原型的技術,以層加工堆疊的方式製作聚己內酯(Polycaprolactone , PCL)多孔性支架,而製作支架Fiber寬度約為130~ 160μm,因此選用線中心距為200、250、300μm之尺寸進行支架製作,其孔徑大小介於70~180μm間,隨後將骨母細胞(MG63)植入、培養於支架內,藉由活性實驗來得知細胞於線中心距為200μm之孔徑支架其成長活性表現最好。並將所製作之PCL支架進行各項物理性質及機械性質之測試,得知PCL藉由有機溶劑氯仿(Chloroform)來溶解,製作支架材料並不會改變PCL的原始性質,且製作之支架具有不錯的機械強度,因而本實驗可作為未來在支架植入於動物體內之實驗參考。
針對所製作之組織工程支架PCL,其整體呈現乳白色,不具透光性,因此培養細胞後無法藉由顯微鏡立即觀測細胞成長之情形,因而使用瓊酯(Agar)為材料,藉由瓊酯具備透明性之優點,來建構組織工程支架,以改善上述之缺點。
Tissue Engineering scaffold is a porous scaffold , it can offer cell an excellent environment to adhesion , grow , differentiate and form ECM , Documents point out that the best porosity of the bone regeneration is under 350μm , but still unable to learn that the influence of porosity size upon cell growth in this range .
Therefore , this research is direct to the best porosity suitable for growth range of the bone regeneration , utilize rapid prototyping technology . Layered manufacturing techniques . Fabricating porous scaffolds of PCL and the width of fiber is about 130~160 μm . Therefore , select the 200 , 250 , 300μm of line diameter to fabricate scaffolds , and porosity sizes are between 70~180μm . To implant and culture the osteoblast cell (MG63) in the scaffold afterwards. Know that cells are the best activity for the scaffold of line diameter of 200 μm porosity by MTT. On the test of every physical property and mechanical property fabrication of PCL scaffold . Know that PCL is dissolved with the organic solvent chloroform . Fabricating the scaffold material will not change nature property of PCL and fabricate the scaffold material has good mechanical intensity . Therefore , this experiment can be consulted as the experiment that implant scaffold in animal's body in the future .
Direct to the fabrication of PCL scaffold of Tissue Engineering , it appears milkiness wholly and does not have opaque quality . Therefore , it can not observe the cell growth immediately with the microscope after culture cell . Then we use the agar as material , through the advantage of transparent quality to build the Tissue Engineering scaffold , by means of this to improve above-mentioned shortcomings .
